User Interfaces: For Data administration and system control one Database Administration user interface is needed (Elmasri & Navathe, 2016). For 4 individual stores in four individual cities 4 individual User Interface will be needed. For Warehouse one Warehouse User interface are needed.
Authentication System: 4 types of authentication protocols or constrains are needed to develop the outer layer of system security. Physical stores authentication system for 4 store User Interfaces, Administration authentication for Admin access, Warehouse authentication for Warehouse to access Internal Server, Customer Authentication for online customer authentication will be needed
Logical operation: The SQL quarry and database processing and normalisation will be connected to the Cloud storage and the SQL server Security protocol (Kimmel, Kleiman & Miller, 2015). To store or fetch data from physical or cloud storage the data must be passed through this logical layer for logical operations and data processing.
Data integrity and server: 2 types of server should be operated by the ABS database Administrator, Internal Server for internal operations and E-Tail Server for E-commerce operation. SQL Server Security system should be used for cyber security of both of these severs (Coronel & Morris, 2016).
Storage System: 2 Types of storage should be used by ABC Clothing company. Physical storage should be used for internal or administrative data storage, such as human resource, business operations and finance. The Cloud storage will be used as real time data storage unit. It will store all products, sales and customer related data (Abadi et al., 2016).
